This standard describes shop-applied, cement-mortar linings specified in the
ANSI/AWWA C100/A21 series of standards for ductile-iron pipe and ductile-iron
and gray-iron fittings for potable water, raw water, wastewater, and reclaimed water
systems and is intended to be used as a supplement to those standards. Major revisions made to the standard in this edition include the
following: scope, purpose and application of standard were expanded to include raw water
applications; addition of definitions for raw and potable water; a new Sec. 4.1.2 Materials intended for use with potable water, was added to include a requirement for testing to NSF/ANSI 61 or FDA Sec. 175.300 of CFR 21 on products if they will be in contact with potable water; and the addition of a provision for manufacturers to use cement mortar that is a blend of ASTM C150 cement with ASTM C595 Type IS, or ASTM C989 cement, with the blend being no less than 50% ASTM C150 cement in Sec. 4.2.
